Answer:
Yellow and Green
Explanation:
It is not blue the graph shows is isnt blue so the colors that absorbed the worse were green and yellow
Blue and red are the colors that plants can absorb the most. The pigments used for photosynthetic processes, such as chlorophyll in plant cells' chloroplasts, are what absorb particular visible-spectrum light wavelengths.
The energy of specific light wavelengths is absorbed by special pigments in chloroplasts of plant cells, resulting in a chemical chain reaction that is known as the light-dependent process of photosynthesis. The best visible light wavelengths for photosynthesis are in the blue (425–450 nm) and red (600–700 nm) ranges.
Chlorophylls do not absorb light at green and yellow wavelengths, as shown by the extremely low level of light absorption between 500 and 600 nm.

When a compound such as X2Z4 is created, what would be the
correct simplified chemical formula?
Answer:
XZ2
Explanation:
There are different ways in which compounds can be represented. Broadly, we have three different types of formula;
- Structural formular: This shows how th atoms in te compound are connected to each other.
- Molecular formular: This shows the actual number of atoms of element present in the compound
- Empirical Formular: This is the simplest formular of a compound. It basically shows the number of atoms in simple ration to each other.
This question requires us to input the empirical formular;
X2Z4
The ratio of the elements is; 2 : 4 which can be simplified into 1 : 2
This means the empirical formular is XZ2

It has been an expense for the Australian government (taxpayers) to try to control the rabbit population
Question 4 options:
True
False
Answer:
true
Explanation:
It has been an expense for the Australian government (taxpayers) to try to control the rabbit population. This statement is true.
Why did the rabbit population grow so quickly in Australia?Aside from the lack of natural predators on the continent, their success is aided by rapid reproduction: They can have more than four litters a year, each with up to five kits (baby rabbits).
The European wild rabbit has become an invasive pest in the southern two-thirds of Australia. They have an impact on natural environments, primary production, as well as townships and infrastructure.
The government turned to biocontrol in the 1950s. They released rabbits infected with myxoma, a virus that only affects rabbits, into southeastern Australia.
Thus, It has been an expense for the Australian government (taxpayers) to try to control the rabbit population. This statement is true.

"No matter what phase water
is in, the water molecules
stay the same; they just move
differently."
1: explain why this evidence matters
Answer:
Yes, water molecules remain the same despite the phase
Explanation:
When water is in the form of ice, it molecules remain the same only the distance between the molecule. This distance is higher than that of the inter molecular distance between liquid water molecules. Due to this reason ice is lighter than water.
Now in gaseous phase, the intermolecular distance increases thereby making it lighter than solid ice and liquid water.

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. The rate of this reaction can be changed by changing the size of marble chips.
Describe experiments to investigate what effect using smaller marble chips has on the rate of this reaction.
Answer:
See explanation
Explanation:
We know that surface area is an important determinant factor in the study of reaction rate. This is the reason why finely divided marble chips react faster than lumps of marble in the reaction between marble chips and dilute HCl.
Now imagine that i have a lump of marble and i have finely divided marble. Then i also have a solution of 0.5 M dilute HCl. If i introduce 1g of the lump of marble into 250 ml solution of the 0.5 M HCl in one beaker and introduce 1g of finely divided marble into another 250 ml solution of 0.5 M HCl in a separate beaker, we will notice that the finely divided marble chips reacts faster as evidenced by the quicker effervescence of CO2 gas from the later compared to the former.
Hence, smaller marble chips reacts faster with dilute HCl than a lump of marble.

When you break an iron magnet into two pieces, you get ____.
two north poles
two south poles
two north poles and two south poles
a piece of iron that is no longer magnetic
Answer:
two north poles and two south poles
Explanation:
A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.
No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.
Answer:
Each piece will still have a north pole and a south pole.

Is MgF2 polar or no polar covalent?
Answer:
ionic
Explanation:
In this instance, fluorine is a non-metal while magnesium is a metal. Ionic bonds are always formed when a metal and a non-metal are combined. Therefore, magnesium fluoride is an ionic compound, and an ionic compound's inter-ion force is always an electrostatic force.
The molecule's ionic bond is exceedingly powerful. When a molecule dissolves in water, it releases a significant amount of ions into the mixture. For the same reason, it conducts electricity as well. This explains why magnesium fluoride is naturally polar.
One type of binary ionic compound is magnesium fluoride. It consists of one magnesium atom and two fluorine atoms. In comparison to fluorine, magnesium is a metal with a substantially lower electronegativity.

oblem: How many molecules of methane (CHA) if there are 9.65 gram of methane ?
Answer:
3.63 x 10²³molecules
Explanation:
Given parameters:
Mass of methane = 9.65g
Unknown:
Number of molecules = ?
Solution:
To solve this problem first, we find the number of moles of the given compound or molecule first.
The given molecule is methane;
CH₄;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of CH₄ = 12 + 4(1) = 16g/mol
Number of moles = [tex]\frac{9.65}{16}[/tex] = 0.603moles
So;
From mole concept;
1 mole of a substance contains 6.02 x 10²³ molecules
0.603moles of methane will contain 0.603 x 6.02 x 10²³
= 3.63 x 10²³molecules
